Value Collection R63034445 Machine Screw 1/4-20 X 2 in

Product Description

The VALUE COLLECTION R63034445 is a 1/4-20 x 2-inch pan head machine screw designed for general-purpose mechanical fastening in trade and industrial applications. Manufactured from grade 18-8 stainless steel with a bright, uncoated finish, this screw resists corrosion in moderate environments where carbon steel fasteners would fail prematurely. The slotted drive accepts a standard flat-blade screwdriver. Thread size follows the Unified National Coarse (UNC) standard at 1/4-20, meaning 20 threads per inch. Length is measured under the head at 2 inches. No washer is included. These screws are sold in multiples of 100 units per order.

This screw is suited for light-to-medium structural and mechanical assembly tasks across HVAC, plumbing, electrical, and general mechanical work. Pan head geometry provides a low-profile, wide-bearing surface that distributes clamping load across the fastened material. Typical applications include securing panels, brackets, junction boxes, and equipment covers where a flat or oval head would not seat properly. The 18-8 stainless construction makes this screw appropriate for installations exposed to moisture, mild chemicals, or outdoor conditions.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and hex nuts
• 2-inch length under head provides sufficient grip for multi-layer panel or bracket assemblies
• Grade 18-8 stainless steel offers corrosion resistance in wet or outdoor environments
• Pan head profile seats flush with or slightly above the work surface, distributing load evenly
• Slotted drive works with standard flat-blade screwdrivers - no specialty bit required
• Bright uncoated finish - no added coating to crack, flake, or interfere with conductivity in grounded assemblies

Compatibility

Designed as a standard 1/4-20 UNC pan head machine screw compatible with any tapped hole, threaded insert, or hex nut meeting the 1/4-20 Unified National Coarse thread specification in inch-measurement fastener applications.

Installation Notes

Install with a flat-blade screwdriver or appropriate bit driver rated for slotted fasteners. De-energize and lock out any electrical equipment before fastening panels or covers per NFPA 70 (NEC) lockout/tagout requirements. Do not overtighten stainless steel fasteners - 18-8 stainless is susceptible to galling under excessive torque; apply a suitable anti-seize compound if repeated removal is expected. Inspect threads in mating holes before installation to avoid cross-threading.
